Augmented reality camera frustum

ABSTRACT

An apparatus such as a head-mounted display (HMD) may have a camera for capturing a visual scene for presentation via the HMD. A user of the apparatus may be operating a second, physical camera for capturing video or still images within the visual scene. The HMD may generate an augmented reality (AR) experience by presenting an AR view frustum representative of the actual view frustum of the physical camera. The field of view of the user viewing the captured visual scene via the AR experience is generally larger that the AR view frustum, allowing the user to avoid unnatural tracking movements and/or hunting for subjects.

TECHNICAL FIELD

The present disclosure relates generally to augmented and/or virtual reality presentations.

DESCRIPTION OF THE RELATED ART

Cameras, such as video cameras and still cameras, can be used to capture an image, a series of images, or a video of a physical, real-world scene. Certain devices, by way of an augmented reality (AR) application or functionality, may be configured to insert virtual objects into the captured images or video before and/or while the images or video are displayed.

DETAILED DESCRIPTION

A camera's field of view can be defined by a view frustum. FIG. 1 illustrates a user 150 filming or viewing a scene through a viewfinder 125 of a camera 120. The view frustum 130 of camera 120 can be represented by a frustum—a portion of a solid (typically a cone or in this case, a pyramid 131) that lies between one or more parallel planes cutting the solid. In this example, the pyramid 131, whose point can originate at the focal point of a lens (not shown) of camera 120, “grows” outward from the lens. A first parallel plane can be referred to as a near clipping plane 133, and a second parallel plane can be referred to as a far clipping plane 135. The view frustum 130 of camera 120 can be defined as a three-dimensional space between near and far clipping planes 133 and 135 within the boundaries of the pyramid 131.

User 150, looking through viewfinder 125, is unable to see anything, e.g., object 140, that is outside of view frustum 130. When trying to capture a scene or frame a shot in which object 140 is moving, user 150 can experience problems. For example, when shooting video, an unnatural follow movement is reflected/recorded as user 150 attempts to re-compose the scene or shot when object 140 comes into view frustum 130. This can also be problematic in the context of shooting still images with camera 120. In such a scenario, user 150 can miss a shot if user 150 must suddenly attempt to track object 140 if the user was not aware of object 140 (or aware of its location and/or movement) beforehand. Moreover, user 150 may have to “hunt” for a lost object, such as if object 140 quickly moves out of view frustum 130. Such problems are exacerbated when camera 120 has a long zoom lens because the field of view of such lenses can be small. Although computer-controlled camera mounts with dedicated object tracking software are available, such camera mounts are not practical for handheld shooting and/or location shots.

In cases where camera 120 is a smartphone camera or similar device without a conventional viewfinder, user 150 may compose a shot using a display of the smartphone in which camera 120 is implemented. Even under these circumstances, the focus of user 150's eyes would be at some distance from camera 120. Far-off objects could be invisible or difficult to see—due to human vision limitations—and user 150's attempt to refocus his/her eyes to infinity while tracking such objects would be difficult if not impossible. For example, looking at a far-off airplane, user 150 would have to re-focus his/her eyes onto a display, such as smartphone display or a rear display of camera 120, and subsequently hunt for that airplane via the display. Attempting to anticipate the airplane's movement as it intercepts another object (another airplane, the moon, etc.) would be difficult for user 150 if not impossible in normal practice. However, such difficulties are overcome by various embodiments disclosed herein.

According to various embodiments disclosed in the present application, an AR view frustum is implemented in an AR experience such that a user can see or detect objects beyond a camera's view frustum. That is, the view frustum of a physical or real-world camera can be virtualized. For example, the view frustum of a camera 320 (see FIG. 3B) can be represented as an AR view frustum 330. This AR view frustum 330 can be presented through an AR device 300 (which can provide a field of view representative of a field of view from the perspective of a user's eyes). In this example, user 350 is able to see beyond the view frustum of camera 320. Accordingly, the user 350 can be aware of any objects, such as object 340, currently outside the view frustum of camera 320 and re-compose or hone in on object 340 before a shot is started. In situations where object 340 moves outside the view frustum or camera 320, user 350 need not hunt for object 340 because the field of view of user 350 is greater than the view frustum of camera 320 (represented by AR view frustum 330) in an AR experience presented to user 350.

FIG. 2 illustrates example processes performed in accordance with various embodiments. At operation 200, a visual scene is captured. The visual scene (an example of which is illustrated in FIG. 3B) may be captured by some form of AR device. FIG. 3A is an example representation of such an AR device 300, which may be implemented as solely an AR device, such as a head-mounted display, a see-through display, an optical see-through display, a video see-through display, a visor, glasses, etc. or as part of another user device, such as a laptop PC. As shown, AR device 300 includes an augmented reality component 302, one or more cameras 304, a display 306, and one or more sensors 308, such an accelerometer 308 a and a tracking unit 308 b.

As used herein, an AR device refers to any device capable of displaying a real-time view of a physical, real-world environment while altering elements within the displayed view of the environment. As such, an AR device displays a view of the real world but augments (e.g., adds or modifies) elements using computer graphics technology. Such an AR device may include and/or be communicatively coupled to a camera device (or multiple camera devices) used to capture a view of the real-world environment and may further include computer software and/or hardware configured to augment elements of the captured scene. When a user looks through or at the AR device, the user sees an augmented view of the physical real-world environment in which the user is located.

The one or more cameras 304 may include cameras for capturing the visual scene. As used herein, a visual scene refers to a view(s) of the real-world environment in which the AR device 300 is being used. For instance, a visual scene may be a series of images of a real-world environment. In the example illustrated in FIG. 3B, the visual scene captured by AR device 300 includes an object 340. Generally, accelerometer 308 a is a device capable of measuring the physical acceleration of the AR device 300. AR component 302 may use the accelerometer 308 a to determine when the position of AR device 300 is changing, for example, which could indicate that the position of the AR device 300 relative to the visual scene is changing.

AR device 300 may be communicatively connected to a camera 320 (which can be an embodiment of camera 120 of FIG. 1). Camera 320 may include a lens 320 a and a tracking marker 320 b. AR view frustum 330 can be representative of the view frustum of camera 320 vis-à-vis lens 320 a. Tracking marker 320 b can be a visual marker, an electronic marker, or other marker that is sensed and monitored by tracking unit 308 b of AR device 300. In this way, the movement and positioning (which can include location, and/or orientation) of camera 320 can be monitored by AR device 300. By tracking camera 320, the AR view frustum 330 can be properly represented by AR device 300. That is, AR view frustum 330 can reflect what camera 320 is viewing in the real-world. Camera 320 can be described or referred to herein as a physical camera, which suggests a real-world camera that can be used by user 350 to shoot still or moving media. Although its view frustum may be represented virtually, camera 320 itself is not virtual.

In some embodiments, camera 320 may communicate its movement and/or position through a wireless connection, such as a near-field-communication (NFC) connection, a Bluetooth connection, etc. The wireless connection can be established through a pairing process, by associating camera 320 with AR device 300 (or vice versa) through the use of a QR code, etc. In some embodiments camera 320 may communicate with AR device 300 through a communication device or dongle that can be connected to camera 320 via a hot shoe mount or other port of camera 320.

It should be noted that in some embodiments, camera 320 may be implemented within or as part of AR device 300. For example, AR device 300 may utilize camera 304 to capture a real-world scene used in providing an AR experience, while camera 320 (implemented in AR device 300) may be used to record video or still images of the real-world scene. In this embodiment, tracking unit 308 b and tracking marker 320 b may be unnecessary because when camera 320 is implemented in or as part of AR device 300, the movement and positioning of camera 320 intrinsically follows that of AR device 300. For example, if camera 320 is located to one side of AR device 300, presentation of AR frustum 300 can be determined with a distance offset from camera 304 and/or display 306. When the positioning of AR device 300 is determined (by AR device 300 on its own or in conjunction with accelerometer 308 a), that distance offset can be applied to the position or orientation determined for AR device 300 to determine the position or orientation of camera 320.

In some embodiments, AR device 300 and/or camera 320 may be connected to a network 310. AR device 300 and camera 320 may communicate through network 310. AR device and camera 320 may utilize one or more features provided via network-based services through network 310, such as face detection, network-provided location determination services, etc.

Returning to FIG. 2, at operation 202, AR component 302 is configured to augment the visual scene with an AR view frustum associated with a physical camera (camera 320 of FIG. 3B), wherein the AR view frustum is smaller than a user field of view (as experienced through AR device 300). As previously described, various embodiments improve upon the use of a camera view frustum 130 (see FIG. 1) by representing the camera view frustum 130 as an AR view frustum 330 (see FIG. 3B) in an AR experience.

At operation 204, movement and/or positioning of the physical camera (camera 320 of FIG. 3B) is tracked. As described above, different methods of tracking the movement and/or positioning of camera 320 can be utilized in accordance with various embodiments. Tracking the movement and/or positioning of camera 320 allows AR device 300 to accurately present AR view frustum 330 to user 350 such that AR view frustum 330 reflects what camera 320 is seeing in its actual view frustum in the real world/visual scene captured by AR device 300. That is, at operation 206, the AR view frustum 330 is at least one of moved and positioned commensurate with the at least one of the movement and positioning of the camera 320. Operations 204 and 206 can be repeated as often as necessary while user 350 is using camera 320.

When user 350 is filming the visual scene using camera 320, user 350 views the visual scene through AR device 300. Because AR view frustum 330 is smaller than the field of view of user 350 (represented by AR device 300), user 350 is able to see object 340 coming into the view frustum 330 of camera 320, or see where object 340 is going as it exits or after exiting view frustum 330. In this way, user 350 can re-compose the shot or scene without the conventional, unnatural follow movement and/or without hunting. This is illustrated in FIG. 3C.

It should be noted that AR view frustum 330 can be presented to user 350 with or without a sighting aid, such as reticle 332. Moreover, the representation of AR view frustum 330 on display 306 can take various forms. In some embodiments, AR view frustum 330 may be a three-dimensional representation (as seen in FIGS. 3B and 3C). In some embodiments, AR view frustum 330 may be a two-dimensional rectangle representative of far clipping plane. Other variations are contemplated.

It should be further noted that in some embodiments, camera 304 may utilize two lenses and image sensors. In this embodiment, one lens and image sensor pair can be utilized for a wider angle peripheral view representative of the field of view of user 350. The other lens and image sensor pair can be utilized for a standard view representative of that of camera 320. In some embodiments, a single image sensor may be used, where the single image sensor is partitioned such that it can process images seen by each of the two lenses.

In some embodiments, rather than user 350 manually moving and/or positioning camera 320, camera 320 can be controlled through a remote control mechanism under user 350's control. In some embodiments, camera 320 can be controlled in response to user 350's movement or position. For example, camera 302 can be configured to follow the movement or positioning of the head or eyes of user 350. In this way, camera 302 will track where user 350 is looking. In some embodiments, controlling the movement or positioning of camera 302 can be performed in addition to tracking and moving or positioning camera 302 (as previously discussed). In some embodiments, for example, when camera 302 is implemented in or as part of AR device 300, or when camera 302 is controlled via a remote-controlled gimbal or tracking rig, camera 302 can be moved or positioned based solely on the movement or positioning of user 350.

In some embodiments, one or more features or characteristics of camera 320 are reflected in the AR experience in addition to or as part of AR view frustum 330. Some of these features or characteristics can include, but are not limited to lens aperture, zoom distance, shutter speed, exposure compensation, focus, and white balance. In this way, user 350 can be made aware of certain specifics regarding the view of camera 320 represented by AR device 300. AR device 300 may be configured to allow user 350 to control one or more of the aforementioned features or characteristics of camera 320 through AR device 300 rather than through a camera 320 user interface. For example, user 350 may adjust the zoom distance of the lens of camera 320.

It should be noted that the size of AR view frustum 330 may be set such that it matches the fixed focal length of camera 320's lens (including its crop ratio). Moreover, the sizing of AR view frustum 330 can be coupled to the zooming information of camera 320's lens electronically (when the lens' focal length is variable rather than fixed). For example, camera 320 may provide zoom information via an application programming interface (API) or some other communicable mechanism. At the very least, user 350 can input maximum and minimum zoom ratios that the lens of camera 320 can provide to AR device 300 which can be depicted simultaneously on display 306. In this way, the size of AR view frustum 330 can vary according to camera 320's operating parameters or characteristics.

Depending on the features or characteristics of camera 320, or depending on any adjustments to those features or characteristics, AR view frustum 330 may also change in a manner reflecting those features, characteristics, or adjustments.

Although various embodiments described in the present application relate to cameras, the use of an AR device to present an AR experience that includes an AR view frustum can be used in other contexts as well. For example, an AR view frustum may be utilized to enhance an aiming device or application.

Software and data transferred via communications interface 424 might typically be carried on signals, which can be electronic, electromagnetic (which includes optical) or other signals capable of being exchanged by a given communications interface 424. These signals might be provided to communications interface 424 via a channel 428. This channel 428 might carry signals and might be implemented using a wired or wireless communication medium. Some examples of a channel might include a phone line, a cellular link, an RF link, an optical link, a network interface, a local or wide area network, and other wired or wireless communications channels.

In this document, the terms “computer program medium” and “computer usable medium” are used to generally refer to transitory or non-transitory media such as, for example, memory 408, storage unit 420, media 414, and channel 428. These and other various forms of computer program media or computer usable media may be involved in carrying one or more sequences of one or more instructions to a processing device for execution. Such instructions embodied on the medium, are generally referred to as “computer program code” or a “computer program product” (which may be grouped in the form of computer programs or other groupings).
